Paper-making CMC Carboxymethyl Cellulose CAS NO.9004-32-4
CMC is used as surface sizing agent. It is with excellent film form
and entire film transferability and it also can form a good closure
and oil-resistance on paper and paperboard surface. Furthermore,
CMC is a dispersant which makes the entire sizing material or
coating material enter into the stable and uniform system, and so
that it will show the good sizing effect.
|2% Solution Viscosity (mPa.s)||≤1000|
|Substitution of degree||0.65-1.0|
|Dry reduction %||≤10.0|
CMC which is applied in surface sizing will shows the effect as
1 . Good rheology, film from and the entire film transferability.
2 . Increase the napping speed of paper, and overcome the paper
surface fluffing and picking.
3 . Improve the surface strength, aeration and curling control.
4 . Improve the paper surface feeling and the printability.
5 . It can form a good closure and oil-resistant on paper or
